Background:Culex quinquefasciatus is the vector that transmit Wuchereria bancrofti that cause lymphatic filariasis. This disease is considered as an endemic in Indonesia. But control using synthetic pesticides is proven to be harmful for human and the ecosystem. Some mosquitoes have also developed a resistance. There is a need to search for a new, safer insecticides. Torch ginger (Etlingera elatior) are known to have larvacidal potentials. In this research, ethanol extract of E. elatior roots were used to test for larvacidal activity against Cx. quinquefasciatus larvae. Objective: To find out if ethanol extract of E. elatior roots have larvacidal activity against Cx. quinquefasciatus larvae. Methods: Varying concentrations of ethanol extract of E. elatior roots are intoduced to larvae of Cx. quinquefasciatus for 24 hours under standardized laboratory condition. Result is calculated with probit analysis. Results: The LC50 and LC90 of the torch ginger roots extract are 2967.163 ppm and 13699.23 ppm (2,97 mg/ml and 13,7 mg/ml), respectively.
